UMBRELLA. BUST-FORM.

Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed March 19, 1913. Serial No. 755,406.

To all whom it may concern Be it known that I, MANES I. HAMBURGER, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Umbrella Bust-Forms, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention consists of a collapsible bust form of what may be called the umbrella type. It is characterized by the provision of a number of vertically extending bendable ribs connected at one end to a common central. supporting member and extensible therefrom to form a frame of the bust form through their connection by struts with a sliding member on a central stem support.

Bust forms are very irregular in section and contour. My invention includes means to take care of these variations whereby a form of this type may be made of any variety of sections and contours. Specifically stated in accordance with the embodiment which I shall herein disclose, this is very simply accomplished by connecting the struts between the ribs and the sliding member on the support at one end for-sliding movement with respect to the connected part.

The base of the form of my invention may be also characterized as being of the umbrella type in that a plurality of radially extensible feet are pivoted at one end to the lower extension of the supporting stem, and may be collapsed to a position parallel and contiguous to the stem itself. The stem support is separable into sections whereby the entire form may be packed when folded into a space only two or three times greater than that of the ordinary hand umbrella.

Referring to the drawings, Figure l is a central vertical and transverse section of the form of my invention showing the same extended. Fig. 2 is a vertical section taken from front to back and also showing the form extended, Fig. 3 is a central vertical transverse section showing the same collapsed together with the stem support separated into sections, Fig. 4 is a horizontal transverse section. Fig. 5, 6, and 7 are details.

Referring first to Figs. 1, 2 and 4:, it will be seen that the form of my invention comprises a plurality of vertically extending ribs 10- 10" which are hinged at their upperends to a central supporting stem 11. They are not hinged directly to the stem, but to an e11- largement 12 of the stem which is of circular shape and adapted to constitute a neck portion of the form, Through struts 13 of various lengths, the ribs 10-10 are connected with a sliding tubular member 14 on the central stem 11. Through the movementof this on the stem, collapsed.

The side ribs 10 are different from the front and back ribs 10 (see Fig.4. and Figs. 1 and 2). The front and back ribs 10 are made of continuous flexible strip material, and are perfectly fiat in cross section as shown in Fig. 4. The side ribs 10 however are made ina plurality of rigid or semirigid sections hinged together at certain points to form joints 14 and adapted when extended to form the contour of the sides of the bust. The hinged joints 14: are located at such points as Will enable the ribs 10 when collapsed as shown in Fig. 3 to most closely approximate a straight line, thus being at the nodal points, or points of greatest convexity of the curves. The struts 13 extending to the sides are connected atthese hinged joints as clearly shown. The connection of the struts 13 with the tubular sliding member 14: is made through slots-15 in the tube shownin' Fi s. 1 and 6. Struts 13 are those struts which partake of maximum move ment less than the maximum movement of thesliding member 1 1. The diameter of the tube 14 is greater than the diameter of the the form may be extended and stem 11 so that an annular space is left be, tween-them. The ball-shaped ends 16 of the struts lie within this space, and are of too large a diameter to pass out of the slots 15.

They may be initially entered within the slots in any chosen manner, as for instance by enlarging one end of each slot and thereafter closingit up, or by forming a small flap section 17, which may be bent outwardly and then inwardly again as shown in Fig. 6. If desired, the struts 13 may be wardly before the tube 14 is assembled upon the stem 11. On account of the length of the slots 15 this may be very readily done, the rib ends of the struts being 1nade small enough to pass through theslots 15. The relative lengths and relative locations of the slots 15 are made such that the tubular member up and down inserted from the inside of the tube 14 outand of varying length as short length struts do not interfere in any Way with the full movement of the tubular member 14 necessary for a complete collapse of the portions of the form which lie the greatest distance from the stem 11. Thus the slots 15 in which the struts having the least movement are pivoted, are made sufficiently longer than the slots in which struts having the greater movement are pivoted to freely permit complete movement of the latter struts. The length of all slots is regulated with respect of course to the maximum movement of the tubular member 14. Thus the shoulder portions which are braced in extended position by the upper struts 13 must be moved a much greater distance through movement of the sliding member 14 than the breast, back and waist portions. The bottoms of the slots 15 are at such points that when the sliding member 14 is in its uppermost position, the inner ends of the struts 13 are braced against the bottoms and in turn bracethe ribs to which they are connected to their fully extended positions.

Obviously the struts 13 having the greatest extent of movement, such for instance as the struts connected with the shoulder portions, may be fixedly hinged to the sliding'member 14 as shown in Fig. 4 instead of being slidably hinged thereto through slots 15. So also the lowermost struts 13 of Fig. 1 connecting with the hip portion of the form. and which have a movement substantially equal to the uppermost struts 13, may be fixedly pivoted to the member 14. Still further the lateral waist struts of Fig. 1 when the waist is not too small may be fixedly connected tothe member 14 by locating the pivot at a point which, when the member 14 is uppermost, lies above the transverse .li'ne connecting the hinged joints of the ribs a distance equal to the distance between the extent, of movement of the shout der struts 13 and the waiststruts 13. Un-

der these conditions the slight stretching of the waist of theform as the waist struts pass the horizontal line is not great. When the waist is small however, the struts should be slidably connected at one end as are the struts of-the front and back of the form. Fixedly pivoting certain of the struts 13 gives a stability greater than may be secured through slidably connecting all of them.

The lateral ribs 10 are padded by material 1 8 as clearly shown in Figs. 1 and 5. The entire frame is covered with burlap or other suitable fabric 19 as clearly shown in Fig. 4, this fabric being sewed together in sections in a manner very similar to the sewing together of a tightly fitting jacket or gown, and suitably attached to each of the several ribs so that there is no harmful displacement thereof when the form is collapsed. Wherever there is strain liable to be imposed when the form is collapsed, the fabric may be loosely secured to one of the adjacent ribs whereby strain may be relieved through movement of the fabric with respect to the ribs. The stem 11 is made in upper and lower sections, the lower section 11 having a socket connection with the upper and being secured thereto by means of a. thumb screw 20.

The base of the form comprises the three radially extending feet 21 which are hinged to the lower end of the section 11 at their inner ends, and while they have free movement upwardly to a position parallel and contiguous to the section 11 as shown in Fig. 3, they have a limited amount of movement only below the horizontal. When in extended position as shown in Fig. 1, they 1 are retained therein by means of a sliding collar 22 on the section 11 which engages in notches 23 in each of the feet 21., and which way be clamped into position upon the section 11 by thumb screw 24. Upon releasing the thumb screw 24, the collar 22 may be moved upwardly to permit the folding of the feet as shown in Fig. 3, whereupon the clamping collar 22 may be pushed over the outer ends of the feet, the collar being of such diameter that it its readily over the chamfered outer ends of the feet. The feet are thus retained in their collapsed position.

hen both the bust and its base are collapsed as shown in Fig. 3, they may be strapped tightly together in a common bundle of very small size, and may be most readily transported in a suitable case by hand, or in a suit case or trunk. .Tn any case, it takes up but a very small space. henever it is desired to use the form, one has only to unstrap the same, extend the base section 11', and place it upon the floor or table, and thereupon grasping the stem 11. with one hand and the sliding member 14 with the other, open the form in the same man-neras one would an ordinary umbrella, and with the same celerity. Opened, it is placed upon the base section 11 and secured thereto by the thumb screw 20. It will. be

observed that the form is held in open pol sition by a latch 25 of the same form that is found in the ordinary umbrella. The form may as readily becollapsed. On account of its lightness and the small space it occupies, several of them of different sizes may be carried by salesmen without encumbcring their baggage in any way.

Fig. 7 illustrates in transverse section a wooden sliding member 14, provided with undercut slots 15 in its surface. In this case, the struts 13 connected with the sliding irember 14 are made with T-heads on the ends as clearly shown. Any other equivalent const'ruction desired may be used.

Although I have shown the best form of my invention now known to me, I desire to have it understood that my invention is capable of many modifications without departing in any wise from its generic spirit. I desire to cover in the annexed claims all such embodiments of my invention.
